"Spatial Image Display Device"

Abstract: Provided is a spatial image display device capable of forming spatial images having a superior reality and high definition.  A spatial image display device  10A is provided with:  a display section 2 including a plurality of pixels 22, and generating a two-dimensional display image corresponding to a video signal; a first lens array 1 including a plurality of first lenses 11 provided in correspondence with the respective pixels 22, and allowing light passing through the respective pixels 22 to converge; and a second lens array 3 converting the converging light, which has passed through the first lens array 1, into parallel light or converging light, and allowing the converted light to pass therethrough.  The light transmitting through the respective pixels 22 in the display section 2 is directed to the second  lens  array  3  after being  converged by the  first  lens  array  1. Accordingly, the light entering the second lens array 3 from the respective pixels 22 behaves like light emitted from a point source, and is converted easily into the parallel light or the converting light in the second lens array 3.
